It seems this season the big bad Moff Gideon, expertly played by Giancarlo Esposito, will be tempting our heroes to the dark side. "It's an iconic battle. I want to disarm him mentally as well," Esposito explained to EW. "You may think I'm a villain, but I'm trying to harness some energy and some powers for a path that could be best for all. You'll get to see [Gideon] be somewhat diplomatic and more of a manipulator."
Esposito also hinted that Gideon will be commanding a "larger vehicle," which we can only assume means a Death Star of some sort. We may also see him team up with Bo-Katan, as she was the last known wielder of the Darksaber, the weapon he acquires at the end of season one.
